[QUOTE="cmillett79, post: 379874, member: 12148"] You just explained one of my greatest concerns Fitch .. This is one thing that I am thinking about..Honestly Id like to keep the barrel length 26" if possible in the 7mm mag..If I have to go 24" or less I would go with a NONmag standard caliber..I once had a 280 and a 7mm mag .. The 280 had a 22" barrel and the mag 24" .. The difference in vel. was min. when pushing "accurate" loads in the same bullet weight..There was no real world advantage with the mag .. This was after a couple months worth of trial loads .. I believe the 280 in 150gr sierras (neck sized) was only 80-120 fps slower than the 7mm mag with the same bullet but loaded for accuracy.. I think the mag was pushing it at 2950+/- and the 280 was a hair over 2850fps.. This is one reason if I saty with the 7mm mag to keep the barrel lengtrh at least 26" ... I wonder if going with a one contour heavier barrel than factory and adding flutes would stiffen it or maybe having it chryo'ed ? [/QUOTE]
